| 橡胶促进剂ZBEC Rubber Accelerator ZBEC 000化学名称Chemical Name 二苄基二硫代氨基甲酸锌（zinc dibenzyl dithiocarbamate） 结构式Molecular Structure
C30H28S4ZnN2 分子量 Molecular Weight 610CAS# 14726-36-4 技术指标 Specifications
性质 相对密度1.14。熔点不小于178℃。溶于乙醇、苯和氯仿，不溶于水。贮存稳定。
用途 天然胶，合成胶及胶乳用超速促进剂。其硫化活性温度较低， 可替代ZDBC、ZDEC、PZ等使用，且操作安全性更佳。尤其突出的是，本品在橡胶加工过程中不会产生致癌性的亚硝胺。本品还可作为噻唑类促进剂的优良的活性剂。使用本品时，氧化锌和硫黄的配合量一般，脂肪酸可用可不用。它可以直接加入胶料，也可以做成分散体加入胶乳。在与食品接触的橡胶制品中的应用，请参照FDA、BgVV有关章节中的规定。
贮存 密封储存在阴凉、干燥、通风良好的地方。避免阳光直射。
包装 复合纸袋，内衬塑料薄膜袋，净重25公斤。
Properties Relative density is 1.14. melting point is above 178℃. Soluble in alchohol, benzene, chloromethane, insoluble in water. Storage is stable.
Applications A overspead accelerator for natural and synthetic rubber and latex. Curing active temperature is low. It can substitute for ZDBC、ZDEC、PZ, ect.. Operating safety is much better. Specially , it will not produce cancer-causing nitrosamize during the rubber manufacturing process , and it can be used as excellent activator to kinds of thiazole. Appropriate matching quantity of Zine oxide and sulfur when using , and aliphatic acid is not necessary .it can be added directly into rubber mass and also can be added into latex as component part. ZBEC is regulated for use in articles in contact with food as specified under FDA 21 CFR 175.105,177.2600 and under BgVV XXI, Categories 1-4 and"Sonderkategorie".
Storage Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight. Packing 25kg net paper bags lined with polyethylene film bags. |
